The crystal structures of bis{3,5-difluoro-2-[4-(2,4,6-trimethylphenyl)pyridin-2-

yl]phenyl-�2N,C 1}(picolinato-�2N,O)iridium(III), [Ir(C20H16F2N)2(C6H4NO2)],

1, and bis[2-(4-tert-butylpyridin-2-yl)-3,5-difluorophenyl-�2N,C 1](picolinato-

�2N,O)iridium(III), [Ir(C15H14F2N)2(C6H4NO2)], 2, are presented herein. These

phosphorescent cyclometallated iridium(III) compounds have been structurally

investigated in order to better understand the nature of their blue-shifted

emssions while maintaining high quantum yields. Compound 1 exhibits

substantial twisting of the mesitylene rings out of the plane of the attached

pyridine ring, with dihedral angles of 67.0 (1) and 78.7 (1)� between the best mean

planes. For both compounds, the contribution of disordered solvent molecule(s)

was removed using the SQUEEZE [Spek (2015). Acta Cryst. C71, 9–18] routine in

PLATON [Spek (2015). Acta Cryst. C71, 9–18]. These solvent molecules are not

considered in the given chemical formula and other crystal data.

1. Chemical context

Phosphorescent cyclometallated iridium(III) compounds have

been investigated for a variety of applications, including solar

cells (Kim et al., 2016), sensors (Marın-Suarez et al., 2012),

bioimaging (Zhang et al., 2015), and scintillators (Bertrand et

al., 2015). However, their most widespread use stems from

their electrophosphorescence and research in this area has

focused on their use in organic light-emitting diodes (OLED)

(Choy et al., 2014; Chi & Chou, 2010; Fu et al., 2011). The most

widely studied blue-emitting iridium complex for this purpose

is bis[2-(4,6-difluorophenyl)pyridinato]iridium(III) picolinate,

or FIrpic (Baranoff & Curchod, 2015). As part of our synthesis

program for plastic scintillators (Rupert et al., 2012; Cherepy

et al., 2015), we have prepared and structurally characterized

several blue-emitting iridium complexes (Sanner et al., 2016).

A recent study by another group has examined the attachment

of alkyl or aryl groups to the pyridine ring of the (difluoro-

phenyl)pyridinate ligand in FIrpic (Kozhevnikov et al., 2013),

resulting in enhanced quantum efficiency, while maintaining

the sky-blue color of the parent complex. We have prepared

and structurally characterized two of those complexes to

examine the structural basis for their superior behavior. We

report herein the crystal structures of bis{3,5-difluoro-2-[4-

(2,4,6-trimethylphenyl)pyridin-2-yl]phenyl-�2N,C1}(picolinato-

�2N,O)iridium(III), 1, and bis[2-(4-tert-butylpyridin-2-yl)-3,5-

difluorophenyl-�2N,C1](picolinato-�2N,O)iridium(III), 2. The

molecular structure of 2 has been reported previously (Laskar

et al., 2006), however, the structure reported below is a new

polymorph.

2. Structural commentary

The molecular structure of complexes 1 and 2 have been

confirmed by X-ray crystallography and displacement ellip-

soid diagrams are shown in Figs. 1 and 2. Both complexes

exhibit the same distorted octahedral geometry with two

bidentate phenylpyridine ligands (coordinated through the

pyridine N atom and a phenyl C atom) and one bidentate

pyridine-2-carboxylate ligand, also known as 2-picolinate

(coordinated through the pyridine N atom and a carboxylate

O atom). The iridium-bound N atoms of the phenylpyridine

ligands are trans to each other, while the phenyl C atoms

bound to iridium are cis. The two ligated atoms in the picoli-

nate ligand are then trans to the phenyl C atoms of the

phenylpyridine ligand. The trans effect of the phenyl groups is

most clearly seen when comparing Ir—N bond lengths. Thus,

the Ir—N(picolinate) bond is on average 0.1 A longer than the

Ir—N(phenylpyridine) bond due to its trans disposition to the

phenyl group. Although there is no such intramolecular

comparison available for the picolinate Ir—O bond (which is

also trans to a phenyl group), we note that the Ir—O bond

length in both these molecules is 2.16 A. This compares with

the shorter value of 2.09 A reported in the Cambridge

Structural Database (CSD; Version 5.39, May 2018, with three

updates; Groom et al., 2016) for an Ir—O bond, again illus-

trating the trans effect of the phenyl group in these molecules.

The C—Ir—N ‘bite’ angle for the phenylpyridine ligand

averages 80.8 (4)� for these complexes, while the N—Ir—O

angle for the picolinate ligand is somewhat smaller at 76.7 (2)�.

The phenyl and pyridine rings in each phenylpyridine ligand

are slightly twisted with respect to each other across the C—C

bond linking the two rings. The dihedral angle between the

best planes for the two rings is in the range 6–10� in these

molecules. A feature of special interest in 1 is the dihedral

angle between the plane of the pyridine ring and that of the

attached mesityl group, e.g. between the N1/C7–C11 ring and

the C12–C17 ring. These values are 67.0 (1) and 78.7 (1)� for

the two mesityl–phenylpyridine ligands in 1. The presence of

two ortho-methyl groups on the mesitylene (e.g. C18 and C20)

presumably causes this large twist of the mesityl ring out of the

plane of the attached pyridine ring. This possibility has been

proposed (Kozhevnikov et al., 2013) as an explanation for the

blue emission of 1 since it minimizes the �-conjugation

between the mesityl and pyridine rings which would otherwise

lead to red-shifted emission. Our results confirm the structural

basis for this proposal.

3. Supramolecular features

Neither complex forms any significant supramolecular inter-

actions with neighboring molecules.

4. Database survey

The molecular structure of 2 has been reported previously

(Laskar et al., 2006; CSD refcode CEHGOM); however, the

structure reported below is a new polymorph as a solvate. A

search of the CSD (Groom et al., 2016) provided no additional

crystal structures related to 1 or 2.

5. Synthesis and crystallization

The title compounds were prepared as described previously

(Kozhevnikov et al., 2013). Diffraction-quality crystals of 1

were obtained by slow evaporation using methanol as solvent,

while 2 utilized a 1:2 (v/v) methyl ethyl ketone–hexane

mixture as solvent.

6. Refinement

Crystal data, data collection and structure refinement details

are summarized in Table 1. All H atoms were placed in

calculated positions and refined as riding atoms; for aryl H

atoms, C—H = 0.95 A and Uiso(H) = 1.2Ueq(C), and for methyl

H atoms, C—H = 0.98 A and Uiso(H) = 1.5Ueq(C). Both

specimens used for this study contained badly disordered

solvent of crystallization. Specimens for compound 1 tended

to lose solvent during mounting. The initial structure solution

appeared to be either a methanol trisolvate or a methanol/

water disolvate, where all three molecules were concatenated

through hydrogen bonds to the O2 hydrogen-bond acceptor.

Only one methanol solvent molecule was clearly indicated, but

it had considerable translational displacements toward a

putative compositionally disordered methanol/water site. The

last member of this chain was likely a methanol, but it was

pathologically disordered. The SQUEEZE routine (Spek,

2015) from PLATON (Spek, 2009) was applied to this disor-

dered solvent region since in least-squares no reasonable

disorder model could be achieved. Void spaces centered at (0,

0, 0) and (0, 0.5, 0.5) totaling 727 A3 were found to contain an

electron count of 177. This electron count would correspond

to approximately ten methanol molecules per unit cell. The

specimen for compound 2 did not appear to lose solvent

during mounting. The initial structure solution found the

expected compound and a region near an inversion center

composed of unknown solvent. The peaks in the difference

Fourier map did not provide any reasonable solvent molecule

(or molecules) after numerous attempts. The SQUEEZE

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
